World’s Largest Cholemanite Reserve


Founded in 1958 in Emet district of Kütahya, Emet Boron Operations Directorate is realizing cholemanite ore production from 2 open quarries as Hisarcık and Espey. The world’s largest and most important cholemanite deposit Hisarcık Espey formation, possesses about 40% of world reserves, and possesses 55% of the reserves in Turkey. The directorate, which has integrated facilities in the processing of boron, cholemanite ore extracted from open quarries is fed to the concentrators for physical enrichment. Concentrated cholemanite produced is milled into ground products in desired sizes. Subsequently, it is transformed to boric acid, which has an important place in the sector after reaction, filtration, crystallization and drying processes. Boric acid plays an active role in eye, ear, skin treatment, insecticide production, fibreglass, LCD screen, Prexy glass production and flame-proof clothing.

Common Uses with Innovation Focused Production

Possessing the largest cholemanite reserves in the world, in Emet Bor Management Directorate, boric acid, concentrated cholemanite, Eticol-Ceramic products are produced. While some of the manufactured products are evaluated in Emet Plant, some of them are sent to Bandırma (Balıkesir) Boron and Acid Factories Operations General Directorate which has become Turkey’s logistics headquarters for borates.
